Letbe a function defined as. The inverse of f is map g: Range
(A)
(B)
(C)
(D)
It is given that is defined as
Let y be an arbitrary element of Range f.
Then, there exists x ∈such that y = f(x)
Let us define g: Rangeas
Now,
∴
Thus, g is the inverse of f i.e., f - 1 = g.
Hence, the inverse of f is the map g: Range, which is given by
.
The correct answer is B.
